This isn't a db thing. The db is merely storing configuration options, which are enforced by the application based on what the end-user has chosen from available choices.
- <a href='https://github.com/texdc'><img border=0 src='https://avatars.githubusercontent.com/u/1590605?v=2' height=16 width=16'></a> And where is the application validating (enforcing) those values?  The db field can be a `decimal(3,0)`, but since PHP doesn't have an `enum` (outside of an extension), the valid values should at least be an array, if not a value object.

At this point it isn't. That's the whole point of my first comment: the commit as it stands right now allows free-form text. 
Changing it to use zen_cfg_select_option(array(\'755\', \'777\', .....) ....) would provide the administrator only a list of radio-buttons from which to choose pre-defined 'safe' options.
